Ullam: Private Diary & Journal

PIN-Locked Journal & Mood Log

Free · In‑App Purchases

A calm, private diary with no account. Lock any diary with its own PIN, track your mood, and keep it all on your iPhone and your own iCloud. Ullam is a calm, private diary for your daily thoughts. No account, no tracking, no servers reading your life — your journal is stored on your iPhone and synced only through your own iCloud. WRITE WITHOUT WORRY • Beautiful, distraction-free editor with rich text, photos and your own emojis • A warm day/night theme that follows the time of day • Color-code each entry by mood, and tag it with a category PRIVATE BY DESIGN • Lock any diary with its own PIN — locked diaries are encrypted with AES-256, using a key derived from your PIN • Face ID / Touch ID unlocks the app; every hidden diary always asks for its PIN • Hidden diaries stay out of your main list and never open without their own PIN • Everything else is protected by your iPhone's built-in data protection and stays on your device or in your personal iCloud. We never see it. FIND ANY MEMORY • Calendar view of your month, with mood at a glance • Filter the calendar by category to instantly find what you wrote • Track your writing streak and daily word goal • Home & Lock Screen widgets: streak, mood, daily goal and a fresh writing prompt OWN YOUR DATA • Start faster with templates: Gratitude, Daily Review, Travel Log, Dream and Goals • Export an encrypted backup protected by a password only you know, and restore it on this or a new device • Share any single entry as Markdown • Moving from Day One? Import your JSON export, photos and tags included — or a folder of Markdown or text notes BRING YOUR DAY IN • Journaling Suggestions on iPhone: pick a moment from your day — photos, places, music, workouts — and Ullam adds it to your entry. Only what you choose is shared with Ullam. • Optionally save each day's mood to Apple Health as State of Mind. Ullam never reads your Health data, and moods in PIN-locked diaries stay in Ullam. ON-DEVICE AI (PREMIUM) • A writing assistant that helps you continue, rephrase or reflect, plus tag suggestions — running entirely on your device • Requires an iPhone that supports Apple Intelligence, on iOS 26 or later FREE & PREMIUM Ullam is free for up to 10 notes, with multiple and hidden diaries, iCloud sync, widgets and mood insights included.
